High thermal stability for extended processing window in high-temperature polymer extrusion.
Low volatility ensures minimal loss during melt processing and long-term retention in final products.
Excellent compatibility with polyolefins, including PP, HDPE, and LDPE.
Synergistic performance when combined with phosphite co-stabilizers or hindered amine light stabilizers (HALS).
Non-staining and low-color formation, preserving aesthetic integrity of transparent or light-colored compounds.
Polypropylene (PP) fibers and nonwovens for medical and hygiene applications.
Automotive interior components requiring long-term thermo-oxidative resistance.
Food-contact packaging films made from polyolefin resins.
Industrial pipes and pressure-rated tubing exposed to elevated service temperatures.
Recycled polyolefin formulations where stabilization against reprocessing degradation is critical.
